  • The biggest integer value represented by double is : 2^53 , for details look here.

  • And the biggest value can be represented with max digits after the point depends on the number itself, but the max number of digits (for example when representing 0.1) is 0.1000000000000000055511151231257827021181583404541015625 have a look at this answer.

  • And the MAX_VALUE represents : (2-2^-52)·2^1023 (have a look at min and max values at this answer)
